TEMPORARY BINDER.

Specification of Letters Patent.

Patented March 5, 1907.

['0 aZZ whont it may concern:

Be it known that I, HENRY J. REUTER, a citizen of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulImprovement in Temporary Binders, of which the following is a full,clear, and exact description, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, forming part of this specification, inwhich Figure 1 is a perspective view of a device constructed inaccordance with my invention. Fig. 2 is a cross-sectional View of thedevice shown in Fig. 1, and Fig. 3 is an enlarged detail view showingthe construction of one of ihe leaf-holding spindles and clampingmemers. This invention relates to devices for temporarily bindingtogether a number of sheets or leaves.

The main object of my invention is to provide a device of the characterreferred to that will be compact, of simple construction and inexpensiveto manufacture, and in which the clamping members will not be liable tocome unfastened accidentally, and thus release the sheets or leaves.

Referring to the drawings which represent the preferred form of myinvention, 1 designates two leaf-holding spindles which project upwardlyfrom a base-plate 2, that is fastened to a cover-board 3. Cooperatingwith each spindle 1 is a clamping member which is substantially Ushapedand preferably formed from a fiat strip of spring metal, the lower leg 4of said member being connected to the base-plate by the spindle, whichextends through said'plate, and the upper leg 5 of said member beingprovided with an opening 6 of greater diameter than the end of thespindle 1, so that said upper leg can be pressed down over the end ofsaid spindle and underneath a notch 7 therein to securely clamp thesheets together, as shown in Fig. 2.

To prevent the clamping member from being accidentally unlocked, aswould be liable to happen if the curved portion of said member wasknocked or subjected to pressure, I have provided the upper leg 5 withan upwardly-projecting lip 8, which extends into an opening or recess 9,formed in the head 1 of the spindle, so that the only way in which theclamping member can be released is by pressing downwardly on said upperleg, as

I shown in Fig. 3. The upper leg can then be bent backwardly, asindicated in dotted lines in Fig. 3, to permit the sheets to be removedfrom the spindles.

I have herein shown the preferred embodiment of my invention as being inthe form of a book comprising two cover-boards 3, that are connectedtogether by a flexible back 3 but it will of course be understood thatthe base-plate and the spindles and clamping members connected theretocould be fastened to a single back piece, and thus produce a devicesimilar to a pad.

From the foregoing description it will be seen that the clamping meansof my device are very compact and occupy but little space, and as thebinder consists of only a few sim ple parts it can be manufactured at asmall cost.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A temporary binder comprising a baseplate having leaf-holdingspindles projecting upwardly therefrom, clamping members cooperatingwith each spindle and consisting of flat pieces of spring metal that areconnected to the base-plate and extend over said spindles, said clampingmembers being provided with openings through which the spindles project,and shoulders on said spindles under which said clamping members extend;substantially as describe d.

2. A temporary binder comprising a baseplate carrying upwardly-projecting leaf-holding spindles that are provided at their upper ends withshoulders, and U-shaped springmetal clamping members connected to saidbase-plate and provide d with openings through which said spindlesproject, the edges of said openings extending underneath the shoulderson the spindles; substantially as described.

3. A temporary binder comprising a baseplate carryingupwardly-projecting leaf-holding spindles provided at their upper endswith notches, a spring-metal U-shaped clamping member cooperating witheach spindle and having its lower leg connected to the base-plate, theupper leg of said member being provided with an opening through whichthe spindle projects, and an upwardly-extending lip on said upper legwhich projects into a recess formed in the spindle when the clampingmember is in operative position, substantially as described.

4 A temporary binder comprising cover- 3 being provided with an openingthrough boards connected together by a flexible back, which the spindleextends, and an upwardlya base-plate connected to one of saidcoverprojecting lip on said leg which extends into boards,upwardly-projecting leaf-holding a recess in the spindle; substantiallyas despindles extending through said plate and l scribed. provided attheir upper ends With notches, l In testimony whereof I hereunto afl'ixmy U-shaped clamping members cooperating l signature, in the presence oftWo Witnesses, with each spindle and being formed from fiat this 8th dayof October, 1906. 7 pieces of spring metal, the lower leg of each HENRYJ. REUTER. of said members being connected to the baseplate by means ofthe spindle With Which it cooperates, and the upper leg of said memberl/Vitnesscs:
